So many better ways to play this hand...

This is in the 6:15 Deepstack 30+3, UTG+1 is a bit of a spaz but not awful, but I don't respect his bets pf. CO is a solid player who I'm not comfortable playing in big hands with. Button just came to the table this orbit. Should I bet out at the flop something like 300 so I know where I am when CO probably just raises me straight up? I felt Button was weak, he delayed a bit before betting, and I didn't feel he had a King, and I felt a minraise would probably cause him to fold.
